GreenerCars – a part of the American Council for an Energy-Efficient Economy – has published a list of 12 cars from 2020 that are worst for the environment.

GreenerCars published its “Green Score Rating” for thousands of 2020 model year vehicles, each of which was given a ranking number between zero to 100.

The “greenest” list is led by Hyundai’s Ioniq Blue and Toyota’s Prius Prime, both of which scored 66 out of 100. The Ioniq Blue gets 57 city miles-per-gallon and 59 highway miles-per-gallon, while the Prius Prime gets 55 city miles-per-gallon and 54 highway miles-per-gallon.

In contrast, the “meanest” car on the list is the Jeep Grand Cherokee Trackhawk four-by-four, which scored a 26 with its 11 city miles-per-gallon and 17 highway miles-per-gallon ratings.

The actual worst vehicle for the environment according to the Green Score ratings is the 2020 Bugatti Chiron, which gets 9 city miles-per-gallon and 14 highway miles-per-gallon. However, GreenerCars did not want to include any vehicle models that weren't "widely available" or didn't meet a certain annual sale number.

"This disqualifies many niche high-end luxury cars and high-performance cars from the list," ACEEE representative Maxine Chikumbo told Business Insider in an email. "I'll note that the absence of these vehicles from the meanest list does not imply that they are somehow 'cleaner' than those on the meanest list - Green Score is still the final say when comparing vehicles."

GreenerCars used the US EPA and the California Air Resources Board's reports, as well as automaker's specifications, to figure out the fuel economy and emissions of all the vehicles in the study. It also estimated pollution from the vehicle's manufacturing and production process and its subsequent air pollution, the release of pollutants that induce health problems, and greenhouse gas emission estimates to develop each vehicle's score.
